FRED A. SCHEUMP, 0F ELKHART, INDIANA.

SMOKE-CONSUMER.

Application filed February 13, 1911.

To all whom it may concern:

Be it known that I, FRED A. SoHRUMr, a citizen of the United States,residing in Elk: hart, in the county of Elkhart and State of Indiana,have invented certain new and useful Improvements in Smoke-Consumers, ofwhich the following is a specification.

My invention relates to smoke consumers of the class in which theproducts of combust-ion are passed through a screen which arrestscinders, sparks and other solid particles and in which the smoke ismingled with steam under pressure before it is passed from the stack,and the object of my invention is to so treat the smoke and otherproducts of combustion that no soot, dirt or black vapor is dischargedinto the atmosphere.

My invention is embodied in a locomotive boiler and in carrying outtheinvention I arrange on the front face of the front tube sheet andsurrounding the ends of the fire tubes, a perforated pipe from whichlive steam is ejected in numerous small jets arranged at differentangles, the jets being directed toward the space beneath a deflectingplate arranged in the smoke box opposite the front ends of the firetubes.

In the front portion of the smoke box there is a screen below which is abaffle plate, beneath the bottom of which the products of combustionpass on their way to the screen. The jets of steam are so directed thatthey converge toward the opening be low the baflie plate and the steamis made to thoroughly mingle with, and act on, the smoke on its waythrough the smoke box and through the screen in the front portion of thesmoke box. A blower consisting of an annular pipe with et nozzles isprovided at the base of the stack through which steam is ejected to acton the smoke as it passes through the ring.

In the accompanying drawings :--Figure 1 shows a vertical section of thefront portion of a locomotive boiler, with my improvements applied. Fig.2 shows a vertical transverse section thereof on the line 22 of Fig. 1.Fig. 3 shows avertical trans verse section on the line 33 of Fig. 1.Fig. 4 shows an elevation of some of the pipe connections.

In the drawings I have shown my invention applied to a locomotive boilerhaving a smoke box, A, arranged in the front of the boiler in advance ofthe front tube sheet, B.

Specification of Letters Patent.

Patented Aug. 1, 1911.

Serial No. 608,421.

The exhaust pipe, C, is arranged immediately below the stack, D, asusual.

C indicates a blow-pipe which is often used in locomotive boilers beingconnected with the steam space of the boiler in the usual way.

A deflector plate, E, is secured at. e to the front tube sheet above thetubes, F, and this plate inclines downwardly toward the exhaust pipe, C,being supported thereon at c. A screen, G, of wire cloth or othersuitable reticulated material extends from the front upper portion ofthe smoke box downwardly and rearwardly, being supported at g on theupper part of the exhaust pipe, G. This screen may be of any suitableconstruc tion. Below the screen is arranged a bafllle plate, H, thelower portion of which is considerably above the bottom 'of the smokebox. This plate may be made in adjustable sections, as shown, toregulate the draft below it. The products of combustion as they passfrom the fire tubes move across the lower portion of the smoke box belowthe deflector plate, E, and under the baffle plate, H. They then passthrough the screen, G, and out through the smoke stack, D. On the frontside of the front tube sheet, B, surrounding the front ends of the firetubes, F, is a pipe, I, provided with numerous openings or jets, i,through which steam is ejected. These jets are set at different anglesand converge toward the space in the smoke box below the baffle plate,H.

J indicates a blower at the base of the stack, D. This consists of anannular pipe, 7', having jet nozzles, 7', through which steam is forcedand suitable pipe connections are provided for supplying the blower, J,and the pipe, I, and the passage of steam through the pipes may becontrolled by suitable valve devices in or near the cab of the engine.

As shown in the drawings the blower, J, is connected by a pipe, L, witha supply pipe, M, and this supply pipe is also connected by a pipe, N,with the jet pipe, I, the particular pipe connections not being of vitalimportance. The arrangement is such that as the products of combustionpass out of the front ends of the tubes they are directed to the spacebelow the deflector plate, H, and at the same time are acted upon byjets of steam passing from the pipe, I, and converging toward the spacebelow the baffie plate. After passing under the baflie plate theparticles of combustion pass through the screen, G, where solidparticles are arrested and drop back into the smoke box, while thelighter particles and vapors pass to the stack where they are furthertreated by the blower, J.

Practical demonstrations have proved that the products of combustion arethoroughly mingled with steam by my apparatus, and the emission of soot,sparks, cinders and black smoke is entirely avoided.

I claim as my invention l. The combination with a smoke box, a fronttube sheet, and fire tubes, of a deflector plate in the smoke box infront of the tubes, a screen in the front portion of the smoke boxthrough which the products of combustion pass, a baffle plate below thescreen, and a steam pipe on the front tube sheet surrounding the frontends of the tubes having perforations directed toward the lower end ofthe baffle plate, substantially as described.

2. The combination of a smoke box, a front tube sheet, fire tubesopening into the smoke box, a stack connected with the smoke Copies ofthis patent may be obtained for five cents each, by addressing theCommissioner of Patents low the screen, and a steam pipe attached to thefront tube sheet and surrounding the front ends of the fire tubesprovided with perforations directed toward the baflie plate.

3. The combination of a smoke box, a stack connected therewith, a fronttube sheet, a steam pipe secured to the front tube sheet and surroundingthe front ends of the tubes provided with perforations directed towardthe lower part of the smoke box, a screen in the front portion of thesmoke box below the stack, and a blower at the base of the stackconsisting of a steam pipe having nozzle jets, for the purposespecified.

In testimony whereof, I have hereunto subscribed my name.

FRED SCHRUMP.
